Is it possible to plot traces that remain for each c value that would
enable viewing parabola envelope in the program below ? There is no
snapshot " Tracer ON " button provided in the popdown menu. Cutting/
pasting each frame is cumbersome to view the envelope.Cannot
DynamicModules be somehow Manipulated to Show them together :) ? I
am sure such feature would be useful if made available in the
Manipulate menu. ( i.e., if not already available as a ready made
program).
Clairaut's Differential Equation of Wolfram Demonstrations Project is
one case in point that I refer to.
Manipulate[ Plot[{ c x - c^2/2 }, {x, -3, 3}, PlotStyle -> {Orange,
Thick}, PlotLabel -> "CLAIRAUT_ c_discr_ EQUN " , AspectRatio ->
Automatic, PlotRange -> {-3, 3}], {c, -2, 2, 0.1}]
